'h all fio/tom z't' 'may concern x lie it known that L @Hennes llli listin,- 'roN, a citizen oit the United States? residing at Bakersfield, in the county oli Kern and State of Celilornia7 lieve .invented new and useful improvements in Fine-Cleaners for Steam-ldoilers5 of? which the following is s specification.

This invention ice-.lates to ilse cleaners for J steam boilers and-.has :for en ohject to provide apparatus of this character wherein means are provided tor connecting s. ,mein .blast pipe with e fluid source such es the boiler itself so that suilicient steain pressure Will he carried to the pipe and then con,

ducted therefrom to the 'holler lines "with the resultant eflee'sive cleaning such nlnes.

Another object ot the invention is to provide a line cleaning Aappeseins which will embody parts that are capable of 'being tolded together and conveniently removed from the boiler Whennot in use.

ln the dmwii'igv forming portion application and in which like "letters erence indicate siinilsr parts in the news1-Figure 1 is a longitndinol section 'through e boiler and through the boiler fines, illustrating the attachment the cleaning apparatus thereto. Fig. Q; is front view ol the boiler showing the application of the line.n cleaner thereto ond illustrating in dotted lines dill-erent positions ci' the blast pipe. 3 is, a longitudinal section through the apparatus showing' the nozthis ' zle in en opened position. Fig'. if is e longitudinal section taken on line lfl oi Fig. 3. 'Fig'. 5 is a perspective view of the nozzle. Fig. 6 is a perspective view oi t'he valve. Fig. 7 is a perspective view ol a portion of the valve rod showing the manner of connecting the controlling levertherewith rlhe apparatus comprises n pipe or mein conduit 1 which is closed et one end as at 2 and provided adjacent to the said closed end with an opening 3 whereby communication is established between the pivoted nozzle 4 and the pipe 1. rllhe nozzle is pivoted at 5 upon the pipe 1, and as illustrated the nozzle is provided with en extension or bracket like portion n which is :movable across a similar extension 'TI -oi? theA pipe 1. A combined nozzle adjusting end valve controlling rod 8 is slidsble longitudinally in the pipe 1 and through the closed end 2 thereof, being provided beyond said closed end with a right angnlerly extending porffliceeetion of Leners Eaten@ fled E91, 19%.

tion ll which extends through en elongated slot 10 in the bracket 7. rlhe portion 9 is pivoted at 11 to one end ot en arcuate link 12, While the opposite end of the latter is pivotally connected at 13 to oit the nozzle Il, Wherehy the nozzle can he adj usted angularly with relation to the pipe 1 when the rod 8 is moved longitudinally in the pipe 1. Plhe nozzle el is provided with a curved discharge end 14: which is ,adapted to 'loe closed by a seat 15 which entends from one side of the pipe 1 es shown in Fig. 3. The rod 8 is slidable through :iT-coupling 16 at the actuating end of the pipe 1. rl'his coupling is connected with s branch pipe l? hy lateral. pipe section 18. The pipe 17 carries e coupling member 19 which may be connected in any suitable Well known manner with s hose which inay lead from eny suitable source of steam supply. A plug 2O closes the branch 2Q of the lcow pli-ng' 1n end es shown the said plug is connected by a radial pipe section 22 with an actuating handle 23, the latter hilo/ing n longitudinal slot Q4 therein for a purpose to be hereinafter explained. rll'he valve rod is provided with e .coller 25 ihrem which eX- tends s. pin 26. i cont-rollinglever 27 is pivoted at 28 to the pipe llwhile the 'opposite end of lever is extended through the slot 24 and into the handle 28 whereby to he guided in its movement thereby. The intermediate portion of the controlling lever- 27 has an elongated slot 29 therein through which the pin 26 of the collar-25 extends whereby to compensate lfor longitudinal adjustments ot' the rod 8. l

rilhe rod 8 is connected with a cylindrical valve 30 which is mounted for sliding Inove- Inents in the pipe 1, being adjustable 'across port openings 31 in the pipe es clearly shown in Fig. 3 whereby when the lever 27 is adjusted to close the nozzle l against the seat 15- the portways 31 Will be opened by said valve,y While 'on another adjustment ot said lever to open the nozzle tothe posit-ionY the extension 6 shown inllig. d or to any other position past y 4iront end oil: the looiler. 'then connected in any suitable source of s' .in supply whereby the steam maj.T he intn .ed to the pipe l and tlicu finally discharged from the nozzle. The lever 2? maj7 oe manipulated to eicct any required an ular adjustment of the nozzle that niigh/ ie deired to bring adsidoralily leej/'ond the ',llho coupling l?) i jacent nues directly in the path of the-dis-A when the valve 30 is in the poz'sition shown' in 191g.' 8

steam emanating from said pas sages will he permitted to relieve said smoke stack and the. smoke liox oi"- the accumulated soot.

l claimzl. A tlue cleaner :for vboilersv comprising* a fluid feeding conduit, a nozzle adjustable angularly thereon and arianged in open connminioation therewith7 a controlling lever at he'intake end of the conduit and a rod Connecting the lever 'with the nozzle, the said conduit having an opening` therein at one side, and a, valve carried by the rod and movable over the said opening on longitudinai adjustments of the rod.

2. il. flue cleaner comprising a conduitV having one of its ends closed and its other end provided With a fluid inlet, a handle on said fluid inlet, said conduit having a lateral passage therein, an adjustable nozzle carried by the conduit and-communicating therewith and located adjacent to the closed end thereof, and means for eliecting adjustment of the nozzle and including a sliding valve in the conduit movable with relation to said lateral passage on dierent adjustments of the nozzle.

3. A flue cleaner comprising a conduit iaving one of its ends closed and its other ,ond provided with a fluid inlet, a handle on said fluid inlet, said conduit having a lateral passage therein,` 'an ladjustable nozzle carried by the conduit and communicating therewith and located adjacent to the closed end thereof, means for effecting adjustment of the nozzle and including a sliding valve.

in the conduit movable with lrelation to said lateral passage on dili'erent adjustments of the nozzle, and a iXed seat eXteIiorly mount.- ed upon the conduit and operable to engage against the discharge end of the nozzle to close the same when the nozzle is projected to one position.
